Verdict

The call

The clearest difference is price: WordReference Dictionary at Free against Dictionary and Thesaurus Pro's $9.99. WordReference Dictionary also leads on update cadence (every 6 weeks vs every 4 months). Dictionary and Thesaurus Pro's advantage is rating (4.9 vs 3.8) and ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
